Growth rates have been outstanding. I’m feeding 37% range cubes. I put 130 6” catfish in my house tank in April. I’ve fed them 220lbs and I just had some kids over to catch a few. I’m getting pound and bigger cats from that stocking and all are very healthy. I’m planning on putting a knife on them when they hit two pounds if I still have water in the tank. It’s getting dry in Tx.
